Everyone loves a good joke, but if you plan on ribbing Nate Diaz, you may need a couple of bodyguards.

Fictional character Renato Laranja, who was created as an inside joke at Eddie Bravo's gym, took media questions alongside Diaz at the World Jiu-Jitsu Expo in May. As usual, the Laranja character was arrogantly boasting about being a 27-time world champion.

Unfortunately, Diaz wasn't in on the joke, and an altercation erupted in the Long Beach Convention Center.

"The Great" Renato Laranja was lucky enough to live to troll another day.

1) Mayhem vs. the World: Nashville Brawl

The Diaz brothers have had their share of crazy moments, but none are more memorable than the "Nashville Brawl."

Jake Shields, a teammate and close friend of the Diaz's, defeated Dan Henderson in Nashville, Tennessee in the headliner on a CBS-televised Strikeforce event.

After the fight, Jason "Mayhem" Miller entered the cage uninvited and asked Shields for a rematch of their November 2009 title bout, but before Shields could answer, Mayhem was attacked by the Diaz brothers.

With the event being nationally televised, it truly was an ugly scene for the sport.

The hope was that people would start looking at fighters as world class athletes and role models, not thugs drunk on inflicting pain.

From now on, Mayhem will probably think twice before entering a cage with the Diaz brothers alone.
